Wherein the puncture head 11 is pointed, blade-shaped or saw-tooth-shaped. It should be noted that, the "head end" in the present embodiment corresponds to one end of the puncture and ablation pen away from the hand that operates the puncture and ablation pen during use, and the "tail end" corresponds to one end of the puncture and ablation pen near the hand that operates the puncture and ablation pen during use.

On the basis of the structure, the outer layer of the hollow puncture needle tube 1 is further coated with an insulating layer 2; the puncture head 11 is exposed out of the insulating layer 2, and the puncture head 11 is generally exposed out of the insulating layer 2 by about 5 mm; with the structure, the hollow puncture needle tube 1 only generates an ablation effect on the puncture head 11 during the use process, but does not generate an ablation effect on the outer side walls of other parts of the hollow puncture needle tube 1, thereby avoiding the generation of an unexpected ablation effect on the outer side walls of other parts of the hollow puncture needle tube 1 to form a blood clot.

Based on the structure, one end of the hollow puncture needle tube 1, which is far away from the puncture head 11, is welded and connected with the stainless steel tube 4, and the inner cavity of the hollow puncture needle tube 1 is communicated with the inner cavity of the stainless steel tube 4, so that body fluid entering the hollow puncture needle tube 1 through the puncture head 11 can enter the stainless steel tube 4. Furthermore, the side wall of the stainless steel tube 4 is provided with at least one through hole 3 for communicating the inner cavity of the hollow puncture needle tube 1; the joint of the stainless steel tube 4 and the puncture needle tube 1 is internally provided with an insulating tube 5; an opening 100 for communicating with the through hole 3 is provided in the insulating tube 5. The insulating tube 5 is made of an insulating material such as, but not limited to, heat shrink plastic. At least one through hole 3 for communicating the inner cavity of the hollow puncture needle tube 1 is arranged on the side wall of the stainless steel tube 4; and the insulating tube 5 is cooperatively provided with an opening 100 for communicating the through hole 3, so that the body fluid entering the hollow puncture needle tube 1 in the puncture process can be discharged in time, thereby reducing the puncture resistance. In addition, in the electrocoagulation process, the body fluid which is vaporized by heating and then enters the hollow puncture needle tube 1 can be timely discharged through the matching of the through hole 3 and the open hole 100, so that the normal electrocoagulation operation is ensured.

In an alternative implementation case, the outer layer of the insulating sleeve 2 is provided with identification rings which are uniformly arranged along the axial direction of the insulating sleeve 2; the spacing between adjacent marker rings may be 10mm to provide a distance display for easy viewing and use by the operator.

In addition, it should be noted that the puncture ablation pen in this embodiment further includes a pen body 6 disposed on the outer layer of the stainless steel tube 4 and adapted to be held by hand, and in an alternative implementation, the insulating tube 5 is adapted to be connected to the pen body 6 by a threaded connection structure. Here, the external thread is arranged on the outer side wall of the insulating tube 5, and the internal thread is arranged inside the pen body 6, so that the threaded connection between the insulating tube 5 and the pen body 6 can be realized.

Finally, it is also necessary to state that the pen body 6 is also provided with an ablation button 92 for activating ablation energy; and a circuit board 91 for connecting the fusion button 61 is also arranged in the pen body 61.

Therefore, the puncture ablation pen of the embodiment has the advantage of wide application range, thereby avoiding the problem of high development and production cost caused by the need of respectively customizing the corresponding puncture ablation pen aiming at the single-needle type ablation structure and the double-needle type ablation structure.

Example 2:
